ROBERT B. FLEMING, OF NIAGARA FALLS, ONTARIO, CANADA moroa-cen-snmnn CLEANER.-

Specification of Letters Patent. Patented June 3 191Q Application filed m 23, 1918. Serial No. 236,136.,

To all whom it may concern:

Be it known that 1, ROBERT BRUCE FLEM- ING, a subject of the King of Great Britain, and resident of the city of Niagara Falls,-

in the countyof Welland,in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Motor-Car-Shield Cleaners, as de-.

scribed in the following specification and illustrated in the accompany ng drawings,

that form part of the same.

The principal objects of the invention are,

to enable the driver toinstantly clear the glass of his wind shield of rain .orsnow,

and to devise'a cleaner which will not mar the glass on the return movement of'the cleaner following its initial action.

The principal feature of the invention consists in the novel construction and arrangement of parts, whereby a cleanlng' member is operated to move direct-1y. down-' ward and upward over the surface of the glass. v I

In the drawings, Figure -1 is an elevational view showing my device folded at the top of the shield.

- Fig. 2 is a front elevational view showing in, full lines the devicefully extended and in dotted lines-an intermediate position.

Fig. 3,is a top plan sectional view. Fig. 4 is an elevational-view'on a small scale of a modification in a folded position.

Fig. 5 is an elevational view of the modified form shown extended.

According to the present invention the cleaning member moves vertically down ward and upward and preferably in parallel relation to" the top of the shield.

In the structure herein shown I provide a bar 1 which is preferably of metal. This is secured to the top outer side of the shield either to the frame of the shield or directly against the face of the glass, a bushmg 2 being arranged adjacent to one end of the bar and extending through the frame or glass and having the nut 3 threaded thereon and clamping it securely in place.

A bolt 4' extends through the bushing 2 and'is adapted to turn therein and upon the outer end of this bolt is secured the arm 5 which is arched slightly outwardly and at its outer end carries a pivotal member 6 which is preferabl formed of sheet metal bent to form a sli ing jaw. The arm 5 is provided intermediate of its length with a looped bracket 7 arranged upon its outer 'tendin parallelism with the top bar.

side and .within the looped portion ofthis bracket are supported the roller bearing\ members 8.

An arm 9 is pivotally secured to the bar 1 adjacent to the end opposite 'to that at which the arm 5 is secured. This arm is provided at its outer end with a pivotal member 10 corresponding to the member 6 arranged upon the outer end of the arm-5 and the length ,of the arm 9 from its pivot point to the pivotal connectionto the memer 10 corresponds exactly to the distancebetween the pivot of the arm'5 and its pivotal member'G.

A bar 11 is slidably arranged within the members 6 and 10. and is provided with a rubber cleaning strip 12 which engages the surface of the glass of the shield. v

The arms 5 and 9 are preferably formed with aslight outward arch in their length in order that they will exert a spring tension .inwardly upon the bar 11 and clean ng strip to hold -it' in close contact with the glass.

The bar 11 extends beneath the bracket 7. secured to the arm 5 between the rollers 8 and is formed with 'a cam-shaped central portion 13 terminating at the upward end-- in. a curve le'and at the other end in a sharp return 15. The shape of this cam is so devised thatupon the swinging of the. arm 5-on its pivot the inward-roller 8=bear ing against the cam surface will swing the arm 9 downwardly at a uniform speed with the movement of the arm in such amanner as to cause the ends of the twoarms to is:-

bar 11 is slidably supported upon the vertical rods 16 rigidly secured to the bar 1 and the downward swinging of the arms 5 and 9 moves the bar 11 011 the rods 16 down- 'wardly parallel to the bar 1, the members 6 .and 10 slidin freely upon the bar.

The arm 5 1s operated by means of a lever 17 secured to the inner end of the bolt 4 on the inner side of the shield. When the bar 11 has been moved to its lowermost position the lever 17 is. swung upwardly swinging the arm 5 in an upward direction so that the roller on the underside engagesthe underside of .the cam 13 andswingsthe arm 9 upwardly in unison with the arm 5, thus raising the cleaner bar 11 in a movement parallel with the top bar.

Both of the. arms 5 and 9 are arched outwardly intermediate of their length and are formed of springmaterial and maintain a spring pressure upon the bar 11 holding the rubber strip 12' carried on the inner edge which may be the frame of the shield.

These arms are preferably formed with offsets 21 midway of their length and they are each pivotally connected to a cross bar 22 at equal distances from the pivot bolts 19.

The cleaning bar 23 is slidably arranged in the pivotal end members 24 and a rod 25 is pivotally connected at one end to the bar 23 and at the other end to the adjacent pivotal connection of the arm 18 and cross bar 22.

One of the arms 22 is connected through the shield at its top pivot to a suitable handle and the manipulation of the handle causes the arms to swing so as to effect a parallel vertical movement of the cleaning bar.

The means shown in Figs. 4 and 5 for maintaining the movement of the cleaner bar in a vertical path may be adapted to the structure shown in Figs. 1, 2 and 3 as indicated by the rod 26 shown in dotted lines on Fig. 3. I,

What I claim as my invention is 1. A motor car shield cleaner, comprising, a rigid support, a pair of arms pivotally secured to said support and operatively engaging each other in sliding contact intermediate of their length, a horizontal'cleaning bar supported on said arms and operated thereby to move up and down, and means for operating said arms from the inner side of the shield.

2. A motor car shield cleaner comprising, a rigid support, a pair of arms pivotally secured to said support and extending downwardly and crossing each other, one of said arms having a cam portion intermediate of its length, means arranged upon the other arm engaging said cam, and a cleaning bar horizontally supported upon the free ends of said arms and. operating vertically.

3. A motor car shield cleaner, comprising, a rigid support, a pair of arms pivotally secured to said support and operatively engaging each other in sliding contact intermediate oftheir length, a horizontal cleaning bar supported on said arms and operated thereby to move up and down, and means engaging said cleaning bar adapted to maintain it in a horizontal position as it moves up and down.

4. A motor car shield cleaner, comprising a rigid bar secured to the shield, a bolt rototably secured in said bar adjacent to one end, an operating lever secured to one end of said bolt, an arm secured to the other end of the bolt on the inner side of the shield, an arm pivotally secured to the rigid bar adjacent to its other end, means carried on the first mentioned arm engaging the second arm. and adapted to raise and lower it in unison, and a cleaning bar carried by the outer ends of said arms and operated in parallelism with the upper bar.

. 5. A motor car shield cleaner, comprising a rigid bar secured to the shield, an arm pivotally mounted adjacent to one 'end' of said rigid bar, means for swinging said arm from the inner side of the shield, a bracket arranged upon said arm intermediate of its length, roller bearings spaced apart arranged in said bracket, an arm piv otally connected to said rigid bar adjacent to its other end and extending through said bracket, and having a cam portion engaging said rollers, and a cleaning bar. carried by the outer ends of said pivotal arms and en gaging the surface of the shield.
